识别隐含Bus-to-Vector转换

Open and simulate modelex_bus_to_vector.

To accept the bus, the Gain blocks implicitly convert the bus to a vector.

To identify buses treated as vectors before simulation, use functionSimulink.BlockDiagram.addBusToVector.

[blocks] = Simulink.BlockDiagram.addBusToVector('ex_bus_to_vector')

### Processing block diagram 'ex_bus_to_vector' ### Number of blocks left that are connected to a bus being used as a vector: 2 ### Done processing block diagram 'ex_bus_to_vector' blocks = 1x2 struct array with fields: BlockPath InputPort LibPath

To identify buses treated as vectors during simulation, set theBus signal treated as vectorconfiguration parameter towarningorerror. The default setting forBus signal treated as vectorisnone, which generates no warning or error message when a block implicitly converts a bus to a vector.

Explicitly Define Bus-To-Vector Conversions

To insert Bus to Vector blocks where blocks implicitly convert buses to vectors, use functionSimulink.BlockDiagram.addBusToVectorwithreportOnlyset tofalse. When you use functionSimulink.BlockDiagram.addBusToVectorwithreportOnlyset tofalse, the function saves the model. To create a writable copy of modelex_bus_to_vector, this example uses thesave_systemfunction.

save_system('ex_bus_to_vector','ex_bus_to_vector_blocks');

[blocks,busToVectors] = Simulink.BlockDiagram.addBusToVector('ex_bus_to_vector_blocks',true,false);

The Gain blocks no longer implicitly convert the bus to a vector. The inserted Bus to Vector blocks perform the conversion explicitly.

Bus to Vector blocks are virtual and do not affect simulation results, code generation, or performance.

FunctionSimulink.BlockDiagram.addBusToVector返回s no remaining implicit bus-to-vector conversions.

[blocks] = Simulink.BlockDiagram.addBusToVector('ex_bus_to_vector_blocks')

###No buses used as vectors left to process blocks = 1x0 empty struct array with fields: BlockPath InputPort MixedAttributes

By specifying acceptable bus-to-vector conversions with Bus to Vector blocks, you can more easily identify unexpected conversions. Having configuration parameterBus signal treated as vectorset towarningorerroralerts you when an unexpected bus-to-vector conversion occurs.
